you can think of it as your normal Fan or Light switch, but instead of you turning it on manually it can be controlled electronically. Technically speaking, BJT is a three-terminal device with an Emitter, collector, and a base pin, the current...
The common-source MOSFET amplifier is related to the CE (common-emitter) amplifier ofBJT. This is very popular due to high gain and larger signal amplification can be achieved. The small-signal and hybrid π model of a common source MOSFET amplifier is shown below. Common Source (CS) Mosfet...
Transistors help build logic gates that act as switches to turn signals on and off in digital circuits. They act as a transistor in an amplifier that we can either turn ‘off’ or ‘on. The digital gates are physical chunks of semiconductor silicon that act as electronic switches. The ‘on...
Thus, this is all about an overview of the2N3904 NPN transistor datasheet. Generally, this transistor is made with Si material and used as an amplifier and switch. Once this transistor works like a switch then it supports 100mA of current. Similarly, it supports 100MHz when it works as an...
Why Choose MOSFET Over BJT? MOSFETs are particularly useful in amplifiers due to their input impedance being nearly infinite which allows the amplifier to capture almost all the incoming signal. The main advantage is that it requires almost no input current to control the load current and that’...

MOSFET stands for Metal Oxide Field Effect Transistor, which has a gate. The gate voltage determines the conductivity of the device. Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like
There are various semiconductor devices like power MOSFET, power BJT, IGBT, and GTO that are used as a switch in buck converter circuits.Thyristorsare not used generally for dc-dc converters because another external communication circuit is required when using a thyristor. Whereas power MOSFET or ...
With a matching antenna, the FM transmitter circuit shown here can transmit signals up to a range of 2 kilo meters. The transistor Q1 and Q2 forms a classic high sensitive preamplifier stage. The audio signal to be transmitted is coupled to the base of Q1 through capacitor C2. R1, R3, ...
of R1 and Rg. Op amp labelled A3 is wired as a standard differential amplifier. R3 connected from the output of A3 to its non inverting input is the feedback resistor. R2 is the input resistor. The voltage gain of the instrumentation amplifier can be expressed by using the equation below...
